Reading the Rubaiyat

Omar Khayyam (1048-1131) was a mathematician who wrote poetry.  Here are two quatrains from his Rubaiyat.

        XLVI

   For in and out, above, about, below,
   'Tis nothing but a Magic Shadow-show
        Play'd in a Box whose Candle is the Sun
   Round which we Phantom Figures come and go.
